SPECIFICATION forming part of Letters Patent No. 268,361, dated November28, 1882,

e Application tiled J' une 1, 1881. (No model.)

To all whom it may concern:

Be it known that we, WILLOUGHBY P. ELAM and WILBUR F. BoGGs, citizens ofthe United States, residing at Petersburg,in the county ot' Menard andState of Illinois, haveinvented certain new and useful Improvements inGrain- Drills; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompan yin g drawings, and toltheletters or figures of reference marked thereonfwhich form a part ofthis specification.

.()ur invention relates to agrain-drill; and the novelty consists in theconstruction and arrangement of parts for the general improvement of thedevice and its better adaptation to the required service, as will bemore fully hereinafter set forth, and specifically pointed out in theclaims.

The invention is designed as 'an improvement upon the device patented tous January 25, 1881, and numbered 237,001.

The invention is fully illustrated in the accompanying drawings, whichform a part ot' this specification, and in which- Figure lis a top planview. Fig. 2 is a vertical section, and Figs. 3, 4, and 5 details.

Referring to the drawings, A represents the main frame Vof a sulkygrain-drill, havingjournais c for the riding-wheels, one of whichcarries a `gear which is properly connected to a pinion uponthefeed-bar,substantially asshown in the patent granted to us andhereinbefore mentioned'.

Upon the front banc', ofthe frame A is secured brackets c, in which arepivoted the forward ends of curved drag-bars C, bifurcated at cl toreceive the foot and leg of the plantingshoe D. The frame G isheld asagainst lateral play by tie-rods c2, as shown, and a vertical rod, U',surrounded by a spiral spring, (l2, which bears upon the upper surfaceof each drag-bar C, and under an arm, E, through which each rod Cpasses, a` headed end allowing the said rods to pass upward as the shoeoverrides obstructions, while the springs exert a constant force to holdthe shoes in action. The bar E operatesloosely in sockets e', formed lin the free ends of arms which arerigidly secured to or upon the axle B.

Secured upon the axle B is a sleeve, f, carrying a toothed segment, F,in which operates aspring-pawl,f, upon atrigger-lever,F, loosely hungupon the shaft B.

y A pedal-lever, G, which also serves as a pivotal bolt for one or moreof the drag-bars, is connected by a spring-pawl, g, to the segment F. Byreleasing the 'pawl g from the segment and 6o employing the lever F thedrag-bars and connected shoe or drill may be lifted out of operation,and this action, through an inclined lug,

m, rigid upon the axle B, operating upon a transverse spring slidingbar, H, throws the arm I or equivalent device outward, and thusautomatically throws the operatinggear out of mesh. i

J represents an arm having perforations j, which connects by a link, j',with an arm, K, 7o rigid upon a bar, K', journaled in the frame A at k,and having rigid arms L, in the sockets t lof which loosely operates aperforated bar, M. Through these perforations operate the vertical rodsN, which are bifurcated below to receive the-axis of the rollers orcoverers O, loosely secured by frames P to the rear portions ot' thedrag-bars. By this construction the link J may be adjusted at will in`the perforations J, and the ooverers have a vertical 8o playindependent of the drag bars or drills, a spring, Q, acting to allow theplay and to eX- ert a constant force to hold the coverers in operation.

It will be observed that'while there is ver- 85 tical play between theplanting and covering devices independent of each other, yet they mayboth be elevated out of operation by the same lever, F.

R represents the feed har or shaft carrying go the feeding-wheels S,having seed-cells .5', and an extended periphery upon each side of thecells, as seen at 8 in the enlarged view, Fig. 5. By this construction`the seed will not be crushed or broken by the cell-partitions.

What we claim as new is- Y 1. The drag-bars C and shoes D, the pivotedrod C', spring O, and elevating means, coinbined with thecovering-wheels 0,'pivoted to the rear ends of the drag-bars, and meansfor roo throwing them in and out; of operation et'. will, as specified.

2. The drag-bars C and shoes D, the pivoted rod C', spring G2, andelevating means, connbined with the covering-wheels 0, pivoted to therear ends el' the dragbars, the pivcted rod and spring N Q5, and meansfor throwing them in and out of operation at will, as specified.

3. The axle B, segment F, lever F', and independently pivored drillingand planting mechzwisni7 combined with means, H I a2, for automaticallythrowing the operating-gear out; of mesh as the planting devices areforced out of operation, as and for the purpose set forth.
